Notion is primarily hierarchical note taker/wiki.
The closest product is Quip but Quip is like Google docs - each page is its own thing. It's not hierarchical.
Airtable is a database. Notion has similar functionality, but not as rich and their tables can be just part of the page, like a picture.
Taskade is a task tracker. I use Notion for a similar purpose but it's not the primary functionality of Notion.
